(Cl. 15-S) 2 Claims.

Thisv invention relates to power driven toy vacuum sweepers.

One of the objects of this invention is the provision of a power driven by toy vacuum sweeper which simulates in appearance and in operation the professional models now currently being used.

Another object of this invention is the provision of a power driven toy, of the character described, which is safely and easily operable by children.

A further object of this invention is the provision of a power driven toy, of the character described, which is durable, simple in construction and cheap to manufacture.

Other objects and advantages will become apparent during the course of the following description.

In the accompanying drawings, forming a part of this specication, and in which like numerals are employed to designate like parts throughout the same,

Fig. 1 is a side elevational View of a toy vacuum sweeper embodying my invention.

Fig. 2 is a plan view of same.

Fig. 3 is an enlarged bottom plan view of the.

toy sweeper.

Fig. 4 is a longitudinal cross sectional View of the toy sweeper.

Fig. 5 is a bottom plan view, with the brush chamber removed.

Fig. 6 is a fractional end view of the brush chamber.

Fig. 7 is a plan view of the brush chamber removed from the housing.

Referring to the drawings, wherein is shown a preferred embodiment of my invention, the numeral Il) designates, generally, a housing formed of a top member I2, shaped substantially as shown, and front and side walls I3 and I4 respectively. The forward portions of the side walls I4 are substantially the same height as the front wall I3 while the rearward portions are of a substantially reduced height.

A brush containing chamber, indicated, generally, by the numeral I6 is adapted to be telescopically received within the forward portion of the side walls I4 and is suitably secured therein, as by bent lugs or ears H which are integrally formed with the Walls I3 and I4. The brush chamber I6 is formed of front, rear and side walls I3, I9 and 2i) respectively, and a bottom 2I integrally formed therewith, the said bottom being provided with a transverse opening 23 to accommodate a rotatable brush 24 and with longitudinal openings 25 to accommodate the supporting wheels 2S, presently to be described. A bottom member 2 is secured to the rear wall I9 of the brush chamber and to the reduced portions of the side walls I4 and serves to provide an enclosed chamber 28 for housing a fan 29.

The top member AI2 is provided with openings S and 3l, the opening 3i) being disposed above the brush chamber It and the opening 3i being disposed above the fan chamber 28. A cap member 32, shaped substantially as shown, is adapted to be secured to the member I2 and serves to house the motor 34, presently to be described. t will be seen that the cap member 32 provides a chamber Sii which communicates with both the brush and fan chambers l5 and 23 respectively. When air is drawn in by the fan through the transverse opening 23, it passes through the brush chamber a, through the motor chamber 35, through the fan chamber 28 and into a bag 3l. Thus, the motor, when in operation, is continuously subjected to a cooling stream of air which serves to maintain same in cool and safe condition.

An axle member S6, suitably mounted in the side Walls 2l of the brush chamber, rotatably supports a pair of supporting rollers or wheels 2S. Spacedly disposed from said axle and suitably journaled in the side walls it), is a rotatable brush member 2d which is provided, at each end thereof, with ixedly mounted friction elements 3Q which are arranged to engage the supporting wheels 26 and to be rotated thereby.

Referring to Fig. 7, it is seen that the axle member 3b is mounted in substantially elongated slots li disposed in the walls it. The said slots permit slight longitudinal movement of the brush 2li in the chamber It. Spring members i3 are adapted to engage the axle member S and the ends of the brush 2li and serve to maintain the elements 3G in frictional engagement with the supporting wheels 25, thus insuring positive rotation of the brush 24 when the toy sweeper is moved over a floor surface.

A trailer wheel 45 suitably supported in a, bifurcated member lit serves as the rear support for the toy sweeper.

The motor 3&3, hereinbefore referred to, may be of any suitable type. It will, however, be apparent that it is desirable to use a motor, in a toy of this character, which is extremely simple in construction and which can be manufactured at very low cost. Accordingly, I iind it preferable to provide a motor which operates on one cycle of an alternating current supply.

Referring to Fig. 4, the motor 34 comprises an enclosed iron frame formed of two substantially L shaped members 41 on which are mounted a coil and core 49 which provide the field for the motor. A rotor or armature 53 is disposed within the eld and is suitably journaled in the frame members 41. One end of the rotor 5) is extended and provided with a knurled portion 5| by which the rotor 5i) may be spun to effect a starting of the motor.

A fan 29 having a plurality of blades is fixedly mounted on the other end of the rotor 53 and depends therefrom, being housed in the chamber 28, hereinbefore described.

A bifurcated member 52 is pivotally mounted on the side walls I4 of the housing and is arranged to accommodate a handle 53 which is frictionally secured thereto, as at 54, by suitable means. Preferably, the handle is formed of two sections 55 and 56 in order to facilitate packaging -of the device. The sections 55 andv 56 are adapted to be assembled and to be secured by a invention, herewith shown and described, is to be taken as a preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resorted to, without departing from the spirit of my invention or the scope of the appended claims.

Cil

I claim:

l. In a vacuum sweeper of the character described a sectionally constructed housing forming a brush chamber and a fan chamber, a motor and motor housing mounted on said sectionally constructed housing and communicating with both of said chambers, said sectionally constructed housing comprising a horizontally disposed member having a depending flange form ing front land side walls, the forwardly disposed portion of said member arranged to telescopically receive a boxlike member forming a brush chamber, the said boxlike member being open at the top and having an intake and opening ings being disposed over said brush chamber and in the bottom thereof, a plate member coacting with the rearward portion of the said side walls and forming a fan chamber, a Vsuction fan mounted on the shaft of said motor and disposed in said fan chamber, said fan being arranged to create a suction whereby air is caused to enter said brush chamber and to pass successively through said motor to cool same during its operation andthrough said fan chamber.

2. In a vacuum sweeper of the character described a sectionally constructed housingforming a brush chamber and a fan chamber, a unitary member forming the top and side walls of said chambers, said member having providedI in the top thereof two openings, one of said openthe other of said openings being disposed over said fan chamber, a Vmotor and motor housing mounted on said unitary member over said openings and providing a continuous conduit for a streamof air passing successively through said brush chamber, through said Vmotor housing, and through said fan chamber.
